Fertiliser Testing
Fertiliser and Nutrient Feed come in many forms. The key to performing accurate testing is in the sample preparation.
Solid fertilizer will need to be mixed with deionised water and diluted to the appropriate concentration. This will normally be 5g of fertilizer diluted to 1 litre.
Once diluted and mixed, you can now treat this sample as if it were a standard water test.
The QP459 Ion Meter is ideal for testing: Nitrate, Potassium, Ammonium, Calcium, Phosphate and Sulphate using 100 and 1000ppm Standard Solutions provided.
Liquid Fertiliser Concentrate:
Preparation is similar where between 2-5 ml of fertiliser is diluted to 1 litre with deionised water.
Once we have a diluted sample we can treat them as if they were standard water samples. You can watch our quick video on our YouTube Channel EDT TV.
Ready Made/Mixed Nutrient Feed:
The normal concentrations allow this to be measured directly using the NPK Meter. The Calcium, Ammonium, Sulphate etc. can be measured using a QP459 Ion Meter.
To expand the testing, use a QPEX8 Meter Kit which allows you to measure pH and EC in addition to the common ions.
